Yesterday Google’s Sundar Pichai said on stage at the company’s I/O conference that 8 out of every 10 phones that shipped worldwide last year were running Android, and that 600 million new smartphone users came online over the past year. That’s a lot of devices running the company’s smartphone OS, and they really want developers to realize the potential of their apps reaching that many people. So much so that they spent over $4 million developing an extensive Android development course in partnership with Udacity.

Google announced today that it’s releasing mobile apps for its Google Classroom service for both Android and iOS devices. The company officially launched Classroom to its Apps for Education customers in the US during the summer offering them a web-based platform for planning lessons, handing out assignments, and working alongside students. Teachers and students will now be able to access those features from mobile devices through the new apps and Google is also adding a could of new features to the platform.
